SPEGIFICATIQN forming part ef Letters Patentino-(654,875, dated July 31, 1900. Y Application inea Novembre 25, issie.,` 'sensi nu. 697.409,.Y ci@ man.) Y

To all whom, it 'may concern.'

Be it known that I, AUGUST'D. COOK, a citizen of the United States,- residing at Lawrenceburg, in the .county of Dearborn and State of Indiana, have invented certain. new and use` ful Improvements in Tube-'Wells; and 1 do -hereby declare the following to be a full,clear,

pipe, or, in fact, anything that it may be de-` siredto support in a well ata point distant above the strainer or above the bottom of the well, where no straineris used. Heretofore in this class of wells difficulty has' been 'experienced in providing an'efiicient or solid foundation for such parts of a well as. the working barrel, foot-valve, inner pump-pipe, dic., or where any part was placed above the lower end of the pipe or well-tube in that the same was subject to slipping or becoming forced downward farther into the well-tube than'yv'a's desired. By my' invention, however, I avoid these objections, all as will hereinafter appear in the following detail description; and my invention consists in certain features of construction hereinafter particularly described, and specifically pointed out in the appended claim.

Referring to the dra-wings, Figure l is a seci tional View ofthe lwer'portion of the welltube or that portion in which my invention is located, the invention being shown as applied.A Fig. 2 is a details'howingr my invention. vFig'. 3 is a ldetail of a modified form" of my iriven` tion.

Like numerals of reference indicate similar parts in the ligures of the drawings.

l designates the usual cylindrical -pipe or well-tube; 2, the support or anchor which constitutes luy-invention, and` 8 the taperedV tubeemployedin 4connection with my support or anchor in a manner hereinafter described, all as shown assembled vin Fig. 1 of the drawings,

l 'In practicing myvinvention I preferto construct the support or anchor from a tube, of brass, the same being, of such diameter as to adapt it to readily slip within the well tube v or pipe. Within the lower end of this tubular support o'r-anchor I '.'rnay locate a ring or annulus 4, which is provided with an annular flange or shoulder arranged to receive the wall of the support or anchor, to which it is secured by riveting or in any'other suitable manner. When in position, said ring constitutes a hold, by which the device as a whole can be raised or lowered, a suitable tool beingemployed for this purpose. From its upper end to a point about midway its length the wall of the support or anchor is at intervals provided with longitudinal kerfs -or slits 5, the.v intermediate portions ofthe metal constituting spring-tongues 6, which may be, and preferably are, slightly spread or deflected before the support or anchor is insertedjnto the WelLtube. lThese springtongues may be formed or provided with any desired means for causing` their upper free ends to engage, frictionally or otherwise,with

the inner surface of the pipe or well-tube;` 4but I prefer to rivet -the upper endof each V.of the said vspring-tongues to the reduced shouldered portionof a segmental jawv 7, the presence of which slightly increases the diameter ofth'e anchor or support.V These jaws 7 may have their outer surfaces roughened or serrated, "as at 8,.00 enable them as a whole to-be forced or driven into supporting engagement with the inner surface of the well-tube, in a-manner hereinafter described.

As shown in 'the modification illustrated in Fig. 3, I may employ a metal ring 9, the same forming a hold, as previously described, and in addition constituting a circular frame or formerin that the spring-tongues 10 are in this instance independently formed and con- -v i sist merely of spring-strips riveted or otherwse secured at their lower ends to the ring. Other modifications ofthe support or anchor will readily suggest themselves, and for this reason I would have it understood that Ido not limit my invention to the precise details of construction herein laid down, but hold that I may vary the same in any manner and to any extent within the knowledge of the skilled mechanic; Y

"1 tube." .This zo tube' 3 is'lo'wered into theupper endjoil the' 'B 'np'poitoranchor and bengforced-down into L nopemfion the@4 As rpport or anchorfis at rst slightly spreadfat itsupp'er end, Aso that vtliefeiame caused the teeth of vthejaatwsto firmly l engage the inner surface ofthe well-tube and maintain 'said teeth in 4s aid engagement, so

r3 that the anehor'is firmly setand-cannot bev farther d ivenfdowlrexcept by, a removal of I f. the tapered tube is of any yield, it will. conform to the shape ofthe v :ze `welltube and compensate foranykirregnlaritiesin the same.' .y -jjvIamLawarl'ethat numerous devices .haine -heretdore beenl employed in connection with the exteriorsf offvarious lkinds of well-pipesg for .the'purp'ose .of aiding in the expansion oi'x ',"ertalingjelastic packings `atdesiredpoints-It thereon. Such devices',' however, have'nothinginfcoinrnon with-my invention, as Ihave nosuch objectinvievv as theferpanson ofa packer, either within or without a well-pipe where a jomtis formed, but yto producean anchor o1' support Wholly Within the well-pipe 'capable of vsustainingthe weight of any part oi the .pump mechanism, as I have heretofore pointed out. In other Words, by the terms' anchor .or support as ,I have employed them in the specification 1 mean merely a seat.

' Having described my invention, what I cla-im is- The ,combination with a well-tube, of atubul'aranchor comprlsing a cylindrical body havingits upper end flared and provided with .kerfs or-slitsforniing spring-tongues. a ring havin gan annulariiange or shoulderarranged to receive the lower'endfof said body, serrated jaws secured to saidtongnes and having reduced flanged portions arranged to receive 'the latter, and accu-ical spreader-arranged to spread said tongues.
